SLIDING DOOR.

SPECIFICATION forming part of Letters Patent No. 359,965, dated March 22, 1887.

Application filed September 25, 1886. Serial No. ill-1.535. (No model.)

To all whom it may concern.-

Be it known that I, CARLOS DYER, a citizen ofthe United States, residing at Lebanon, in the county of G rafton and StateofNew Hampshire, have invented certain new and useful Improvements in Sliding Doors 5 and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters and tigures of reference marked thereon, which form a part of this specification.

The object of my invention is to so hang the door on two single trucks that it will slide within a partition on a single track and require a pocket substantially no wider than the door is thick; also,to have the door-hanger adjust able and attached to astrip fastened to the top of the door; also, to provide the inner edge of the door with rubber bunters of peculiar construction and adjustable; also,to stop the closing doors at the center without jar; also,to have the supporting-strip for the top casing removable, so that the truck may be easily repaired or readj usted; also, to have the vertical studs and boards, which form the pocket and all parts around the door and truck so put together as to be easily taken apart.

My invention consists in details of construction, described below, and set forth in the claims.

In the drawings, Figure l is a side elevation in broken section, showing one door only, the arrangement of the outer truck, and the removable parts, the inner truck being broken away with the door. Fig. 2 is a horizontal broken sectionnear the top of the door, which is back in the pocket. Fig. 3is a vertical broken sect-ion,chietly showing the parts above the door. Fig. 4 is a side elevation, broken away, showing the lower rubber bunter on the inner edge of the door. Fig. 5 is a plan View, broken away, showing the manner of stopping double doors at the center. Fig. 6 is an end elevation of the truck and bed removed.

Like letters refer to like parts.

a represents the door, and b the casing. To the top of the door is strongly fastenedastrip,

o c, of wood or metal, (see Figs. l and 3,) and to the jambs d is attached rubber friction-strips 4e, for preventing rattling and undue lateral movement of the doors. 'Io the strip c, alittle back of the outer edge of the door, is attached the door-hangerf. The lower portion ofit has slots c', provided with set screws c2, whereby the door may be adjusted when out of true hang. The strip c is very important, as the hanger is attached and adj Listed upon it alone, and the woodwork of the door proper is not cut into at all, as is the case where long screw arms or rods and a turn-wheel are used to adjust; furthermore, my construction does not render it necessary to bring long hanger-arms down upon the outside of the door; also, bythe use of said strip the top ot' the dooris brought so near the track as to prevent any running off. The sheave g is journaled by a steel pin, t, in the upper part of the hanger, the slotf being horizontally long, for the purpose of lateral adjustment if a change inreither becomes necessary. The track h, which may be of rubber to deaden the sound, or of any suitable material, is oval, and is attached to a bed, lt', strongly bolted to one of the strips t' i', (see Fig. 3,) which are fastened to the'vertical side studs, a, and the boards m m. One of these strips-for example, -should be left oft" until the door is hung, and both are easily removablc, making it convenient to repair or readjust the sheave or hanger. The beam k above the sheave should be as wide as the door-pocket.

Z Z2 is a ground for the lath and plaster Z. Z2 and m m are also boards ou either side of k.

The door-pocket is formed by the vertical studs n and the boards o, o', o2, and o3, all ot' which, except o3, are united by tongue-andgroove joints. (See Figs. l and 2.) This con struction dispenses with the use of nails, and allows the pocket to be quickly set up, and in view ofthe method of hanging the door the pocket need not be substantially wider than the thickness ofthe door. In double doors the other pocket would simply be a reversed construction of the one shown.

At two suitable points on the inner edge of the door,near the top and bottom,there are arranged two hollow rubber bunters, p, which strike the furring o, when the doors ,are run back and relieve the hangers from strain and jar. Each bunter rest-s on a disk, p', within the door, and back of this is a spiral spring, p2,

adjusted by means of said disk and a set-screw, p3, so that the bunter at the top will strike at the same time.

The manner of stopping double doors at the center without jar (see Fig. 5) is as follows: A strip or stop, r, having sides shod with rubber at r 1", and being of the same thickness as the strip c on the top of the door, is fastened transversely on the bottom of the removable stripsz' i. The strips c c, coming together with the doors, (but not being as long as the door top,) will strike against the rubber sides 1" r and stop the door, the tongue s on one door having meanwhile entered the groove s in the other. Where asingle door is used,it is only necessary to put a rubber tip, x, on the end of strip c. (See Fig. l.)

I do not deem it necessary to show both bunters p in one view, as they are separately shown in Figs. 2 and 4; nor do l deem it necessary to show both trucks or double doors in position, as the description of one will enable any one skilled in the art to properly arrange two. Care should be taken, however, to arrange the inner truck so as to exactly correspond oppositely to the location of the one shown.

VIt will be seen that by properly locating the single trucks the door or doors may be run back and not require a pocket wider than the door, and four sheaves and a single track will answer for double doors.

By making all the parts about the door and pocket removable great convenience and saving of labor are gained when readj ustment or repairs are required,and by the Inode of hanging at thetop of the door it runs so near the track as to prevent ruiming oil'.

Having fully described my invention,what l desire to claim and secure by Letters Patent 1sl. The combination, with the oval rubber track h, of the sheaves g, having pin t, the hangers f, provided with lateral slot f ,vertieal slots c', and set-screw c2, the strip c, and the door a, as set forth.

2. The combination, with the door, they sheave-hangers, the sheaves, and their single track, of the removable furring t, as set forth.

3. The combination, with the furring i, of the track-bed 7L', bolted thereto, the track h, the sheaves,and adjustable hangers g f, the removable furring z", the door a, and its top strip, c, as set forth.

4. The combination, with a sliding door hung substantially as shown, of the removable supporting-strip for the top casing, the beam k, the boards m m, and the ground Z for the lath and plaster Z' Z2, as set forth.

5. The combinatiomwith theinnerend ofthe door, of the rubber hunters, consisting'of the hollow rubber portion p, the diskp, the spring p, and the set-screw p3, as set forth.

6. The combination, with the removable furrings t' z", of the transverse strip r, having rubber sides r 1", and the doors a a, provided with top strips, c c, adapted to strike against the rubber sides r' r when the doors meet at the center, as set forth.

In testimony whereof l afiix my signature in presence of two witnesses.

CARLOS DYER.
